Chromatographic separation of ethanolic root extracts of Taraxacum laevigatum and Taraxacum disseminatum afforded a total of eight germacrane- and eudesmane-type sesquiterpenoids. including new compounds, 1beta,3beta,6alpha-trihydroxy-4alpha( 15)-dihydrocostic acid methyl ester and its 1-O-beta-glucopyranoside. Their structures were established by spectroscopic analyses. In addition, the structure of 4alpha(15), 11beta(13)-tetrahydroridentin B-1-O-beta-glucopyranoside was elucidated by extensive NMR studies.
对光果蒲公英和小花蒲公英乙醇根提取物进行色谱分离，共得到8种吉马烷型和桉叶烷型倍半萜类化合物，包括新化合物1β,3β,6α-三羟基-4α(15)-二氢木香酸甲酯及其1-O-β-吡喃葡萄糖苷。通过光谱分析确定了它们的结构。此外，通过广泛的核磁共振研究阐明了4α(15),11β(13)-四氢齿孔菌酸B-1-O-β-吡喃葡萄糖苷的结构。
